The Shadow - 1933. This is not the shadow that "knows what evil lurks in the hearts of men;" this shadow is a blackmailer, and the bad guy.
It stars Henry Kendall, Elizabeth Allan, and Felix Aylmer. More information can be found on the IMDB website, if you're into all that. As for me, I just like watching old movies!
The source for this upload can be found elsewhere on archive.org. I cleaned up the audio and decided to share it back to this site.
